Things to Do in Keflavík — Southern Peninsula: Top Attractions, Tours & Tickets

#1Blue LagoonMustBlue Lagoon and Svartsengi4.6(33,000)

This is the Southern Peninsula’s marquee experience and the strongest reason many first-time visitors build time into a Keflavík stop. Treat it as a deliberately booked spa outing rather than a quick roadside photo stop, especially if it is your arrival or departure-day splurge.

3h Sells out — book weeks aheadBook the first slot of the day or a later-evening entry.

Reserve a timed entry well ahead for peak travel dates and aim for an early or late slot.

#2SeljalandsfossMust4.8(3,700)

One of Iceland’s defining South Coast waterfalls and a classic first-timer stop because of its unusually immersive setting. Plan it as part of a full South Coast day, with weatherproof clothing and enough time not to rush onward immediately.

45m FreeArrive early or late; midday tour-bus traffic is the least pleasant time to visit.

Pairs with: Skógafoss · Dyrhólaey · Vik

#3SkógafossMust4.9(4,700)

A powerful, immediately legible Iceland waterfall that belongs on a first South Coast itinerary. It is more compelling than a quick photo stop: linger for changing light and use it as a natural anchor between Seljalandsfoss and Vík.

1h FreeEarly morning is best for space around the base and easier parking.

Pairs with: Seljalandsfoss · Dyrhólaey · Vik

#4SnæfellsjökullMust4.6(241)

The glacier-capped volcano is the geographic and visual centerpiece of a Snæfellsnes circuit. Appreciate it through the peninsula’s coastal drives and trails; visibility is weather-dependent, so do not build a rigid itinerary around one view.

1.5h FreeMorning can offer the clearest views before cloud builds, though conditions change quickly.

Pairs with: Arnarstapi · Vatnshellir Lava Cave · Svöðufoss

#5Viking World (Tourist attraction)ShouldNjarðvík

The main indoor cultural stop near Keflavík, centered on Viking history and a replica ninth-century ship. It is modest rather than destination-scale, but worthwhile for travelers with time before a flight or for those who want context before seeing Iceland’s landscapes.

1h Walk upGo near opening if a tour group is expected later in the day.

Walk-up admission is normally practical; check seasonal opening hours before making a special trip.

Pairs with: Blue Lagoon · Giantess Cave (Tourist attraction)

#6DyrhólaeyShould4.8(5,600)

A dramatic South Coast headland with broad views over black-sand coastline and the sea. It is a worthwhile stop only as part of a longer southern Iceland road trip; it is not a realistic Keflavík side trip.

45m FreeGo early or near dusk for clearer views and less crowded pull-offs.

Pairs with: Vik · Skógafoss · Seljalandsfoss

#7Vatnshellir Lava CaveShould4.6(1,800)

This is one of the more accessible ways to experience Iceland’s volcanic underworld on the Snæfellsnes Peninsula. It works best for visitors who want a guided geological experience to break up a long scenic drive.

1h Book aheadChoose an early tour, then continue around Snæfellsnes before the busiest roadside stops fill up.

Book a tour ahead in summer or when your Snæfellsnes itinerary has little flexibility.

Pairs with: Snæfellsjökull · Arnarstapi · Bjarnafoss

#8LandmannalaugarShould4.8(1,000)

A highland landscape for travelers who want Iceland beyond the standard ring-road stops, with hiking and geothermal scenery as the point rather than a quick viewpoint. It requires a properly planned day and should not be casually added to a Keflavík itinerary.

5h FreeStart as early as transport and conditions allow; weather and access are central to the experience.

Pairs with: Thórsmörk

#9KirkjufellShould4.6(1,500)

The photogenic mountain near Grundarfjörður is one of Snæfellsnes’s signature landscape stops. It is best approached as one scene in a peninsula circuit, not as an all-day destination from Keflavík.

40m FreeVisit early or around evening light; the main viewing area is busiest in the middle of the day.

Pairs with: Stykkishólmur · Snæfellsjökull · Arnarstapi

#10VikShouldOld Keflavík Waterfront

Vík is the practical South Coast base and a worthwhile scenic pause, rather than a single-ticket attraction. Use it for a meal, supplies, and coastal views while connecting Dyrhólaey and the major waterfalls.

1h FreeOvernighting or arriving early makes the village more pleasant than a midday coach-stop visit.

Pairs with: Dyrhólaey · Skógafoss · Seljalandsfoss

#11VestmannaeyjarShould4.7(29)

The Westman Islands make a rewarding overnight or long-day detour for travelers who want a distinct island landscape rather than another roadside stop. Give the islands enough time to justify the transport; they are not a casual add-on from Keflavík.

6h Book aheadTake an early departure and avoid treating the final return connection as optional.

Reserve ferry or flight transport ahead in busy periods, particularly if taking a vehicle.

Pairs with: Seljalandsfoss · Skógafoss

#12ThórsmörkShould4.8(179)

A dramatic hiking area for visitors prepared to trade convenience for one of southern Iceland’s more immersive landscapes. Access and conditions matter as much as sightseeing, so it suits a dedicated excursion rather than a rushed self-drive detour.

6h Book aheadDepart early and allow a full weather-buffered day.

Book transport or a guided excursion ahead if you are not independently equipped for highland access.

Pairs with: Landmannalaugar

#13ArnarstapiShould

This small Snæfellsnes coastal settlement is useful as a base for sea cliffs, walks, and volcanic scenery rather than as a town to tour at length. Pair it with nearby natural stops and allow time to walk rather than merely photograph the harbor.

1h FreeWalk the coast early or later in the day, after the largest driving groups have moved on.

Pairs with: Snæfellsjökull · Vatnshellir Lava Cave · Bjarnafoss

#14Whale Watching from Keflavík HarbourShould

A harbor departure gives Keflavík a genuine sea-based activity beyond airport logistics, with the chance to see dolphins, orca, minke, and humpback whales. Make it a half-day commitment and regard wildlife sightings as possible rather than guaranteed.

3h Book aheadEarlier departures often feel less crowded; sea conditions matter more than the clock.

Reserve ahead in the main travel season and choose a departure with a cancellation policy that works for your schedule.

Pairs with: Keflavík Harbour Waterfront Walk and Lighthouse · Giantess Cave (Tourist attraction)

#15Giantess Cave (Tourist attraction)If timeGarður

A quirky, brief local stop built around a folkloric giantess rather than a major Icelandic landmark. Use it as a family-friendly diversion while walking Keflavík’s waterfront, not as the reason to make a special journey.

20m Free

Pairs with: Viking World · Keflavík Harbour Waterfront Walk and Lighthouse

#16SvöðufossIf time4.8(641)

A handsome, less-famous Snæfellsnes waterfall that rewards travelers already exploring the peninsula. It is a short scenic pause rather than a standalone must-see, particularly appealing if you prefer quieter stops to Iceland’s headline waterfalls.

30m FreeMorning and evening are quieter than the middle of a summer driving day.

Pairs with: Bjarnafoss · Arnarstapi · Snæfellsjökull

#17StykkishólmurIf time

A pleasant harbor town and a civilized pause on the northern side of Snæfellsnes, especially for travelers who enjoy coastal settlement character as much as scenery. It is better for lunch, an overnight, or a waterfront walk than for a rushed detour.

1.3h FreeVisit in the morning or stay overnight to experience it outside day-trip traffic.

Pairs with: Kirkjufell · Snæfellsjökull

#18BjarnafossIf time4.8(53)

A quiet and attractive waterfall on Snæfellsnes that earns its place as a short scenic stop, not a major destination. Add it if you are already driving between the peninsula’s larger sights and want a lower-key contrast to crowded waterfall stops.

25m FreeStop outside the midday rush when the small parking area is easier to use.

Pairs with: Arnarstapi · Svöðufoss · Vatnshellir Lava Cave

#19Keflavík Harbour Waterfront Walk and LighthouseIf time

The waterfront path is the best low-effort way to see Keflavík as a coastal town rather than simply an airport base. Follow it toward the lighthouse, watch for seabirds, and use it to link the harbor with the Giantess Cave.

1.3h FreeWalk it in the evening for quieter paths and softer coastal light.
